About me
Web3 & Full-Stack Developer with a strong focus on building real-world blockchain applications. I specialize in smart contracts, dApp development, and Web3 integrations using React, Next.js, TypeScript, and ethers.js. I have hands-on experience working with wallet connections (MetaMask, WalletConnect), transaction flows, and blockchain-based architectures. I’ve built and deployed a full Web3 platform, including frontend, backend, and smart contracts, which gives me a deep understanding of debugging and optimizing Web3 applications. I’m comfortable jumping into existing codebases, identifying issues quickly, and delivering efficient solutions. Currently open to freelance opportunities and ready to collaborate on impactful Web3 projects.
